Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | Thermon’s cybersecurity risk management system is a comprehensive framework that helps the Company identify, assess, and mitigate known cybersecurity risks. The system is designed to protect the confidentiality, integrity, and availability of the Company's information assets. The system includes a risk assessment process that identifies and assesses the Company's cybersecurity risks. The risk assessment process is based on the security principles set forth in the National Institute of Standards and Technology ("NIST") Cybersecurity Framework and includes the following steps: •Identification of assets •Identification of threats •Identification of vulnerabilities •Assessment of risk The system is primarily implemented by the Company's cybersecurity team. This team is responsible for: •Developing and implementing the risk assessment process •Developing and implementing the risk mitigation strategy •Developing and implementing the risk monitoring and reporting process •Training the Company's employees on cybersecurity risk management The Company's cybersecurity risk management system is reviewed and updated on an annual basis. This includes a comprehensive incident response plan. The review process is designed to ensure that the system remains effective and efficient as the cybersecurity threat landscape evolves. The Company currently uses a third-party system for training our people on cybersecurity risks as well as strategies to mitigate those risks through interactive learning and tests. The Company tracks the compliance and performance of the relevant people who participate in the training. At least annually, the Company's Board of Directors (the "Board") receives updates regarding the cybersecurity risk profile and the effectiveness of the Company's cybersecurity risk management program. Monitoring is another key component of the cybersecurity risk management system. We employ 24/7 monitoring and regular testing to mitigate threats and possible weaknesses. Additionally, we maintain insurance coverage for cybersecurity attacks.
